The Austral Volcanic Zone (AVZ) is a volcanic arc in the Andes of southwestern South America. It is one of the four volcanic zones of the Andes. It is one of the four volcanic zones of the Andes. The AVZ extends south of the Patagonian Volcanic Gap to Tierra del Fuego archipelago, a distance of well over 600 mi (1,000 km) .
The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. The Andean volcanism is a result of the subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones that are separated from each other by volcanic gaps.
Part of the Central Volcanic Zone of the Andes, it rises 5,672 metres (18,609 ft) above sea level. The volcano's summit is cut by a 1.4-kilometre-wide (0.87 mi) and 150-metre-deep (490 ft) caldera, which itself contains a smaller crater. Below the summit, Ubinas has the shape of an upwards-steepening cone with a prominent notch on the southern ...
The western volcanoes of Bolivia are part of the Central Volcanic Zone of the Andes, a major upper Cenozoic volcanic province. [8] Volcanic eruptions in Bolivia are scarce, the latest one occurred in Irruputuncu in 1995. Volcanic hazards do not represent any threat to the major populated centres which are all in the eastern Altiplano or further ...
There is an additional volcanic belt south of the Southern Volcanic Zone, the Austral Volcanic Zone, [7] associated with the subduction of the Antarctic Plate. [8] Sabancaya is located in the Central Volcanic Zone of the Andes, which extends through southern Peru. [9] Many volcanoes in the Central Volcanic Zone are poorly known, owing to their ...
Huaynaputina (/ ˌ w aɪ n ə p ʊ ˈ t iː n ə / WY-nə-puu-TEE-nə; Spanish: [wajnapuˈtina]) is a volcano in a volcanic high plateau in southern Peru.Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate.
Socompa is a large stratovolcano (composite volcano) on the border of Argentina and Chile. It has an elevation of 6,051 metres (19,852 ft) and is part of the Chilean and Argentine Andean Volcanic Belt (AVB). Socompa is within the Central Volcanic Zone, one of the segments of the AVB, which contains about 44 active volcanoes.
Part of the Central Volcanic Zone of the Andes, its highest summit is 5,868 metres (19,252 ft) above sea level and features a summit crater that opens to the south. The western rim of the summit crater is formed by a compound of lava domes , the youngest of which features a vigorous fumarole that is visible from afar.
